Erythromycin is the top preferred antibiotic in treating acne, especially when it comes to its milder level. The goal of this medicine is to eradicate the bacteria Propionibacterium acnes, disease’s promoter. To get better and faster effects, doctors recommend mixing Erythromycin with Vitamin A-based topical retinoids. It is important to have a prescription. Customers may choose between a gel, solution, or ointment. Don’t use it more than two times in a day – skin irritation is often the only side effect.
